APPARATUS FOR HEATING CARS WITH HOT AIR.

SPECIFICATION forming part of Letters Patent No. 376,138, dated January 10, 1888 Application filed Marchla'), 1887.

To all whom, it may concern:

Be it known that we, MONTGOMERY CASSEL- MAN and THOMAS F. MOGANN, citizens of the United States, residing at Minneapolis, in the county of Hcnnepin and State of Minnesota, have invented certain new and useful Improvements in Apparatus for Heating Cars with Hot Air, of which the followingis aspecification.

Our invention relatcsto apparatus for warming cars by hot air supplied from a separate car.

The object of the invention isto separate the heater from the cars to be warmed to avoid danger from fire in case of accident to the cars; and theinvention consists, generally, in introducing fresh air to a chamber heated by steamcoils' and forcing the warmed air thence by means of a blower and pipes to the cars.

The invention is illustrated in the accom: panying drawing, in which the figure shows a plan of the car containing the heating apparatus and a portion of one of the cars to be warmed.

In the drawing, A represents the car containing the heating apparatus,and Bone of the passenger-coaches coupled to the car A.

G is a steam-boiler,with which is connected at steam-pipe, 0, leading to a 'coil or coils, D, in a tight compartment,E,of the car. cis the return-pipe from the coils.

F F are pipes extending from the sides of the car A to the compartment E for the induction of fresh air. Nings e, pivoted centrally to the mouths of the ducts F, with theirlongersides inwardly, adjust themselves according to the direction of the cars movement to create a draft into the pipes when the car is in motion. The airintroduced through these pipes to the compartmentE becomes warmed by the coils, and a suitable fan, G, at the opposite side of the compartment, draws the air from the compartment and expels it into a second compartment, 1

erated simultaneously.

When the cars are moving in the direction Serial No. 230,978. (No nu del.)

indicated by the arrow 2, the air in the C011]- partment F is forced into the pipesfat the rear side of the compartment. To these pipes are connected, by ordinary couplings, 7c, the pipes f which extend into the cars B. The pipes f extend along the floors of the cars, preferably into boxes b, which are provided with registers r at proper intervals,and damp ers'r' are provided for the registers. 3, may be used to connect the dampers at each side of the car, so that all of them can be op- When the movement of the cars is in the opposite direction,or when the cars are attached to the opposite end of the heating-car, the pipesf are coupled to the pipes f, which communicate with the compartment F at the side opposite the pipes f. Valves 2) v are provided at the entrances ofthe pipesff for shutting off the inlet to the pipes which are not connected to the pipesf". Levers m in the engine-room are connected by rods m with these valves for ciosing the inlets to the respective pipes, as maybe required by the location of the heating-car relatively to the cars to be heated.

H is an engine for operating the fan by means 'ot' a crank-rod and crank h, shaft 1', and gearingj, or other well-known devices.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s-- The eon1bination,with thecar A,of the com- A rod,
